Differences between agrocenoses and biogeocenoses.

Agrocenosis is a piece system created by human activity, biogeocenosis – by nature. An example of an agrocenosis: fields, vegetable gardens, orchards, parkland. Agrocenosis is similar to biogeocenosis in that: there are organisms – producers, consumers and destroyers of organic compounds; the circulation of substances in a given area; plants here are the primary link in the food chain. The differences are that: in the agrocenosis there is a small number of species, usually only one species; small food chain, no circulation of substances; many animals of the same species, for example, pests.
